TI中文支持网请问PCM9211支持HDMI 2.1 eARC 标准的帧的专用输入，是否同时支持HDMI音频输入。
Kailyn Chen：
应该是支持的，请看这篇应用手册对ARC和eARC的介绍：www.ti.com/…/sbaa300a.pdf
One of the most important functions the ARC enables is sending audio signal both “upstream” and “downstream” over a singleconnection. As a result, with eARC the full-resolutionsound signals can be passed back and forth betweenyour TV and audio systems with ease and without compromising sound quality.
